CUPYWHOLDER.

SPECIFICATION forming part of Letters Patent No. 640,347', dated January2, 1900. Application filed December Z0, 1898. Serial No. 699,858. (Nomodel.)

To all whom, 'it may concern,.-

Be it known that l, ORLANDO R. WmsLow, a citizen of the United States,residing at Marsh iield,in the county of W'ebster and State of Missouri,have invented a new and useful Copyllolder, of which the following is aspecihcation.

My invention relates to a combined bookrest, copy-holder, and guide, andhas for. its object to provide a simple and efficient improvement uponthe construction shown and described in Patent No. 551,825, granted toHubbard and Winslow on December 24, 1895, the particular object of thepresent invention being to provide means whereby the adjustableline-guide may be varied in position toward and from the plane of theholder, and thus caused to traverse paths at diiferent distances fromthe plane of the holder to adapt the apparatus for holding either loosesheets or books of different thicknesses, while providing for thecontact of the guide with the surface of the sheet or leaf throughoutits movement.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

.ln the drawings, Figure 1 is a perspective view of a copy-holderconstructed in accordance with my invention, the parts being arrangedfor use in connection with a book. Fig. 2 is a front view showing theparts arranged Afor use in connection with a sheet. Fig. 3 is a detailview of the traveler by which the guide-arms are carried. Fig. 4 is aninverted plan view of a portion of the holder to show the means formaintaining the combined guide-bar and holding-arm in its properposition with relation to the back of the holder. Fig. 5 is a verticalsectional view of the same. Fig, 6 is a detail view of the adjustableyoke by which the combined guide and holding-arm is supported. Fig. 7 isa rear perspective view of a portion of the apparatus to show the meansfor securing the standard at the desired adjustment. Fig. 8 is a detailsection of the idle pulley and the means for adj ustably mou nting thesame upon the holding-arm.

Similar reference characters indicate corresponding parts in all thefigures of the drawings.

The back of the book-holder embodying my invention consists of leaves 10and 11, which are spaced apart at their adjacent edges to form aninterval sufficient to receive the binding of a book, and these leavesor sections are connected near their lower ends by aforwardly-projecting rest 12 and near their upper ends by a transversebar or cleat 13, bowed rearwardly to form a stirrup 14 in the plane ofthe space or interval between the adjacent edges of the leaves orsections. In the offsets or shoulders at the extremities of this stirrupare formed sockets 15 for the reception of the inturned trunnions 1G atthe extremities of the separated upwardlydivergent arms 17 of a backbrace or leg 1S, which may be formed of heavy springwire or theequivalent thereof. Also extending rearwardly from the back of theholder is a ratchet-arm 19, arranged in operative relation with one ofthe arms of the back brace or leg and having a series of seats ornotches in which the adjacent arm of said back-bracc is adapted toengage to lock the latter at the desired adjustment with relation to theplane ofthe back. The resilience of the arms of the back-brace serves tomaintain their terminal trunnions in the sockets and also to hold one ofsaid arms in engagement with the desired seat or notch of theratchet-bar to prevent accidental disarrangement of the parts.

Mounted for swinging movement in a vertical plane centrally of theinterval between the adjacent edges of the leaves or sections of theback is a book-holding arm 20, adapted to lie in the binding-crease of abook throughout the length of the latter, and in the constructionillustrated said arm is provided at its lower end with a transversespindle 21, terminally mounted in bearings in the arms 22 of a yoke 23.This yoke is provided with a rearwardly-extending slide-plate 24,longitudinally slotted, as at 25, to receive a guide block 26, dependingfrom or otherwise permanently attached to the rest 12, and threaded in asuitable socket in said guide-block, preferably i rom the under sidethereof, is a thumbi screw .27, having a shoulder to bear against ICOthe lower surface of said slide-plate and clamp the latter at thedesired forward and rearward adjustment, thus securing the spindle ofthe book-holding arm in the desired position with relation to the planeof the back of the holder. Springs 28, coiled upon the spindle of theholding-arm and attached at its extremities, respectively, tothe spindleand the yoke, serve to repress the holding-arm at its upper end and thusmaintain it yieldingly in engagement with a book supported by the rest;but it will be understood that other equivalent means may be employedfor thus yieldingly holding the arm in its operative position, whileallowing the forward-swinging movement thereof to turn the leaves of abook or to remove and replace the same. Also extending radially from thespindle of the holding-arm, and preferably mountedr in a diametricalbearing therein, is the spindle 29 of a pulley 30, having a thumb-holdvor grip 3l, and traversing this operating-pulley and also a second oridle pulley 32, near the upper end of the holdingarm, is a carrier 33,consisting of cord or any other equivalent iiexible device, the sides ofsaid carrier being arranged approximately parallel with the holding-arm.The tension of this carrier may be adj usted by the adjustment of theidle pulley, which is mounted upon the holding-arm for movement paralleltherewith by means of a slide 34, which is locked at the desiredadjustment by a setscrew 35. `Said set-screw im pinges terminallyagainst the surface of the holding-arm and is shouldered and otherwiseconstructed to form a spindle for the idle pulley.

Mountedy upon the holding-arm between the transverse planes of theoperating and idle pulleys is a traveler 36, and the holdingarm isvpreferably of cross-sectionally-round construction, while-theguide-opening in the traveleris of similar cross-sectional constructionto adapt the traveler to turn or rock freely upon the holding-arm as acenter. This traveler carries oppositely extending guide-arms 37, saidguide-arms being of extensible construction, with movable members 38,mounted to slide on those members which are attached to the traveler.The outer extremities of the main or .fixed members of the guide-armsare constructed to form keepers 39, through which the adjustable membersextend, and said adjustable members, at their inner ends, are providedwith keepers 40 to traverse the fixed members. This traveler is attachedto one side of the carrier, and hence by communicating rotary movementto the operating-pulley, and thus communicating motion kto the carrier,the traveler may be advanced upward or downward upon the holdin g-arm asa guide to arrange the upper edges of the guide-arms in the desiredrelations to lines of printing or writing upon the copy, whether thelatter is a book or a sheet suitably spported'upon the rest or fastenedby means of a clamp 4l to one of the leaves or Sections of said rest. Asa means of attachment of the carrier to the traveler I preferably aflixto the latter a clasp 42, consisting of a fiat plate or its equivalent,engaged at its center by a screw 43, threaded into the body portion ofthe traveler and terminally free, the extremities of said clasp beinglocated adjacent to the plane of the guide-arms. One extremity of saidclamp is bifurcated, as shown at 44, and the extremities of the carriermay be engaged therewith, as indicated in the drawings. The extremitiesof the clasp, however, perform the further function of engagingthekeepers at the inner ends of the adjustable members of the guide arms.

"When said adjustable members are moved inward, the said keepers passunder the extremities of the clasp or between the same and the plane ofthe body portions of the guide-arms and are thus secured to preventaccidental extension, while disengagement may be effected by drawingoutwardly upon the adjustable members with sufficient force to overcomethe frictional resistance offered by the extremities of the clasp.

From the above description it Will be seen that an open book may bearranged upon the holder embodying myinvention, the side portions ormembers of the book-back occupying positions, respectively, upon theleaves or sections of the back, while the binding occupies a position inthe interval or space between said leaves or sections, and by looseningthe set-screw by which the yoke 23 is secured in place the lower end ofthe holdingarm may be adjusted toward and from the plane of the back tocause said holding-arm to lie throughout its length in the bindingcreaseof the book, said set-screw being tightened, Vafter said adjustment, toclamp the parts in the desired position. In the same Way, as indicatedin Fig. 2, a single sheet or a plurality .of loose sheets may bearranged in contact with one leaf or member of the back, where it may besecured by any suitable means, such as the clamp shown and described,the adjustment of the yoke being suited to the thickness of the object,whether a book or loose sheets, which may be arranged upon the rest tocause the guide-arms to travel in a path parallel with the surface ofsaid object. The extension of the guide-arms in opposite directions fromthe plane of the holdin g-arm adapts the apparatus to indicate thedesired line upon either side of a book supported by the rest.Furthermore, the swiveled mounting of the traveler upon the holding-armadapts the guide-arms to lie in flat contact with the opposite sides ofa book when the latter is opened other than at the center or when aportion of a book upon one side of the plane of the holding-arm is ofgreater thickness than the other, and the liexibility of the carrierallows this angular adjustment of the guide-arms Without aifecting theoperativeness of the parts.
